■ Nokia battery authentication
Always use original Nokia batteries for your safety. To check that you are 
getting an original Nokia battery, purchase it from an authorized Nokia 
dealer, look for the Nokia Original Enhancements logo on the packaging, and 
inspect the hologram label using the following steps:
Successful completion of the four steps is not a total assurance of the 
authenticity of the battery. If you have any reason to believe that your battery 
is not an authentic original Nokia battery, you should refrain from using it, 
and take it to the nearest authorized Nokia service point or dealer for 
assistance. Your authorized Nokia service point or dealer will inspect the 
battery for authenticity. If authenticity cannot be verified, return the battery 
to the place of purchase. 
Authenticate hologram
1. When looking at the hologram on the label, you 
should see the Nokia connecting hands symbol 
from one angle and the Nokia Original 
Enhancements logo when looking from another 
angle.
2. When you angle the hologram left, right, down, 
and up, you should see 1, 2, 3, and 4 dots on each 
side respectively.
3. Scratch the side of the label to reveal a 20-digit 
code, for example, 12345678919876543210. 
Turn the battery so that the numbers are facing 
upwards. The 20-digit code reads starting from 
the number at the top row followed by the bottom 
row.
